Talking to an AN Int'l Flight Attendant recently as well as a friend of mine in CX who had the melancholy duty of informing the AN 747 crew that their airline had ceased trading.
This great man (unmentioned) offered to ring around other CX crews to see if they could be billeted out for the night or until a flight could be found.
Those involved know who they were and this is what truly makes for the term professionals.
As for Air NZ turning away AN crews stranded (and in particular those with confirmed space tickets) I believe AN is better off without them.
Once liquidation is announced the true bidders will materialise and commence fighting over whats left of AN's hide.
We truly live in interesting times.........
